一般过去时学习

2011/10/13 22:25:44
 

1.一般过去时的构成

肯定式:动词原形加词尾-ed构成   否定式:由助动词did not+动词原形构成

疑问式:助动词 did+主语+动词原形构成

be和have有自己的构成方式(以work为例):

动词 肯定式 疑问式 否定式
be

I/He/She/It was

We/You/They/ were

Was I/he/she/it...?

Were we/you/they...?

I/He/She/It was not...

We/You/They were not...

have I/He/She/It/We/You/They had Had I/he/she/it/we/you/they...? I/He/She/It/We/You/They had not...
work I/He/She/It/We/You/They worked... Did I/he/she/it/we/you/they work...? I/He/She/We/You/They didn't work...

2.与一般过去时连用的时间状语

   一、yesterday,last night(week,year,month,Sunday),then,at that time,at that moment,just now,a few days(weeks,months,years) ago等。

   二、由after,before,when,while引导的表示过去的时间状语从句。

   三、一般过去时也可以与today,this week(month,year)等时间状语连用,但这些时间状语应指过去。如:

   Did you see him today? 你今天见他了吗?(today 指今天已过去的某一时刻)

3.一般过去时的基本用法


    表示过去的动作或状态。一般过去时在表示这个意义时多有明确的表过去的时间状语,或有上下文暗示。如:

    1、She turned on the light after she went in the room. 她进屋后开了灯。

    2、He died 5 years ago. 他五年前去世了。

    3、He came back the day before yesterday. 他是前天回来的。

    4、She was in Beijing some years ago. 几年前她在北京。

    5、Who put forward the proposal? 谁提出的这个建议?

    表过去的习惯动作。如:

    1、We often practiced swimming last year. 去年我们经常练习游泳。

    2、When he was in Beijing,he came to see me every week.他在北京时,每周都来看我。

    用于谈论或评价已死的人。如:

    1、Shakespeare wrote a lot of plays.莎士比亚写了很多戏剧。

    用于描述一些发生时间不清楚但肯定是过去发生的事情。如:

    1、I was happy to hear from you. 很高兴收到你的来信。

    2、What was the final score? 最后的比分如何?

    3、I am sorry I didn't see you. 对不起,刚才没有看见你。

    4、I thought you were out. 我原以为你出去了。

    可用来表示已完成的动作。如:

    1、I wrote a letter yesterday. 我昨天写了一封信。

    2、I read two books last week. 上周我读了两本书。

    可用于表示现在的情况,体现委婉客气的语气。如:

    1、Did you want anything to drink? 你想要点喝的东西吗?

    2、Could I have a look? 我能看一下吗?

    3、Did you want me? 你找我吗?

    4、I wondered if you could help me to mail this letter.不知你能否帮我寄这封信。

    5、I hoped you would help me.我希望你能帮帮我。

    用于转述原本为一般现在时的直接引语。如:

    1、He said he didn't like swimming. 他说他不喜欢游泳。

    2、He said he was at work. 他说他在工作。

    3、He told me that he would leave the following week.他告诉我他下周动身。

    用于虚拟语气中,表示现在或将来时间的动作或状态。如:

    1、It's high time we went. 是我们该走的时候了。

    2、It seems as if I were a monster.好像我是个怪物似的。

    3、I wish I were a bird. 我要是只鸟多好。

    4、I would buy the car if I had the money. 我要有那笔钱我就买下那辆车。
